[gentoo-user] Forcing X.org video driver without xorg.config

[Black Napalm]

Hello!

I am trying to set up X.org and the Gentoo X Server configuration
HOWTO says that HAL should be used and that xorg.conf should only be
used as a last resort. However, when running X without a configuration
file, it autodetects the video card and tries to load the wrong
drivers, which I haven't installed, and therefore fails.
Is there a way to force X to use a specific driver without using a
configuration file? I am not really familiar with HAL, but it seems as
though none of the provided policies have anything to do with video
cards.

Thank you in advance!
